DA9063
System Power Management IC (PMIC) for applications
providing up to 12 A continuous current
DA9063 is a powerful system PMIC for single-, dual-, and quad-core application processors
such as those based on the ARM Cortex-A9TM and Cortex-A15TM architectures.
The DA9063 follows a scalable approach of output currents and rails to supply the entire
system and is capable of delivering a total of up to 12 A from its six DC-DC buck converters.
High efficiency is achieved over a wide load range by automatically selecting Pulse
Frequency Modulation (PFM) or Pulse Width Modulation (PWM) modes. All bucks use
integrated power switches, removing the need for external Schottky diodes. A high switching
frequency allows low-profile inductors to be used. Two bucks can be combined in a 5 A dual-
phase configuration, two offer a merged configuration for a combined 3 A, and one can be
used as a DDR VTT supply. Eleven SmartMirror™ LDO regulators with programmable output
voltage provide up to 300 mA each.
All LDOs support remote capacitor placement and can operate from a low voltage supply. This
allows the LDOs to be cascaded with a suitable buck to improve overall system efficiency. A number
of LDOs can be configured as current-limited bypass-switches to support external peripherals.
Processor core leakage is reduced by using the integrated rail switch controller to control external
FET switches for ultra-fast power domain switching.
Controlled by a programmable digital power manager, the 17 user-programmable switched/linear
regulators may be configured to meet the start-up sequence, voltage, and timing requirements
for most applications. The power manager includes supply-rail qualification and system reset
management. Dynamic Voltage Scaling (DVS) is available to achieve optimal processor energy-per-
task performance. Dialog’s patented SmartMirror™ dynamic biasing is implemented on all linear
regulators.
Power mode transitions can be triggered with software control,
GPIOs, or with button control.
Several types of button press can be used to trigger different
power mode transitions. DVS can be realised via the I²C
interface or GPIO control.
The low-power Real Time Clock (RTC) with an external crystal
oscillator provides time-keeping, alarm and wakeup functions.
In addition, a watchdog timer is included for system monitoring
purposes.
